This cassette tape on staff attitudes toward educational change is one of a series designed to inspire inservice school personnel and provide them with basic information about school innovation. In this 20-minute tape, Allen outlines several principles of introducing and sustaining change in a school. His goal for a school is to achieve "critical mass," that is, enough school personnel committed to change to make trying out and adopting or discarding changes a way of life. Allen believes that schools experience failure from being too cautious about change, which frustrates a staff geared for a change, and from expecting successful results from change too soon. He closes the tape with a list of questions school personnel should ask themselves when they are considering changes. (LP)
